IMPROVED REVERSIBLE CHAIR.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that/I, WILLIAM H. J OECKEL, of the ,city, county, and State of New York, have invented a new and improved Reversible Chair; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 represents a vertical transverse section of my improved reversible chair.

Figure 2 is a detail top view, partly in section, of the same.

Similar letters of reference indicate corresponding parts.

This inventionhas for its object to provide a simple device, whereby, on such chairs which have reversible backs, the seat will be inclined backward wheuever the position of the back is changed.

The invention consists in the application of a cam to the pivot' of the back, working between forked cars that project from the pivoted seat. Whenever the back is turned over, the cam will' be turned with it, to change the position of the seat.

A, in the drawing, represents one of the two posts or end supports of the chair. Both are made of castmetal or other suitable material.

B is the seat, hung between the posts A. It has,

at its ends, upward-projecting' arms a a, which are, by pins bb, pivoted to the posts A, some distance above the seat. The latter is thus suspended from and can swing on said pivots.

G is the back of the chair. Ithas projecting arms, d d, which are, by pins 0 c, pivoted to the supports A, some distance above the pivot-s b. On the arms d or pivots d are formed cams f, which fit between the forked upper end of the arms'a. The cams turn with the arms d. The cams hold the arms-a somcwhatinclined, and with them the seat, as in fig. 1. When the back is reversed, the cams turn and reverse the inclination of the seat, so that it is always higher in front than in the rear.

This invention is applicable more particularly to railroad-chairs, for which it will be very. useful. The same effect will be produced by having the cams fixed on the arms a, and the forks on the arms (I.

Having thus described my-invention,

I claim as new, and desire to secure by Letters Patent A reversible chair, on which, by neans of cams f,

the seat will be adjusted when the back is reversed,

substantially as herein shown and described."
